OT Networks Secured Without Slowing Production

ICS (Industrial Control Systems) security has to account for uptime, legacy systems, and safety systems that can’t simply be patched or rebooted the way office IT can. Assessments and fixes are purpose-built around keeping production lines running and throughput high.

IT/OT segmentation separates business networks from the control systems running production, so a breach on one side doesn’t automatically reach the other. It’s one of the first steps in most industrial cybersecurity assessments, and one of the most effective compensating controls available for older systems that can’t be patched directly.

Gray’s risk-based assessments are guided by NIST and IEC frameworks, evaluating a facility’s networks, control systems, and remote access against recognized ICS security standards.

Yes. Gray designs secure remote access for vendors, integrators, and internal teams who need to reach control systems, so third-party vendors and other outside users only gain access to what the job requires.

Food and beverage, consumer packaged goods, life sciences, chemicals, advanced manufacturing, and data center operators all run control systems that depend on OT security, not standard IT security. Critical infrastructure organizations in particular are increasingly targeted, since outdated protocols and previously air-gapped systems offer an easier attack vector than a modern IT network.

No. Gray’s approach is built around keeping systems running efficiently. Segmentation, monitoring, and access controls are designed to enhance security and reduce the attack surface without adding downtime or complexity to daily operations.
